Actually, Larry, the Italian VNA can be used for filters, etc. On the analyzer web site, Davide posted info on adding a second BNC fitting to provide IN and OUT ports for this purpose.
I finally got my unit working. Thought there was a problem with it, but it turned out to be in my laptop instead. I'll be making that mod in my unit. 73, Bob N6WG -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Larry Phipps Sent: Wednesday, April 13, 2005 9:07 AM Cc: Elecraft List Subject: Re: [Elecraft] Potential Elecraft Kit This looks like a nice little analyzer. I have used the AD8302 and it does a decent job within its 60 dB range limitation, which should be enough for most measurements. Since it has its own oscillator, I assume the levels are permanently set to maximize dynamic range. Note that it is a one port device, however, so it can't measure DUT input vs. output parameters such as gain and phase and other parameters between input and output.
